Computers have always been the most important aspect of technology. Ever since mathematician John Von Neumann, inspired by the success of ENIAC, began an abstract study of data processing which ultimately proved that basically anything can be done with a computer, we started to slowly notice just how revolutionary these devices can be.
But, a computer can’t really do much stuff by itself, and that’s when us humans step up. The reason for that is the fact that computers are machines that need a set of instructions in order to do something, to execute a program, etc. That’s why we need software, that’s why we need programming, and that’s why we need programming languages.
